The slagging and degassing methods in the smelting process of aluminum and aluminum alloys can generally be divided into flux covering and inert gas protection methods; chemical reaction and adsorption methods, namely flux and gas refining methods; non-adsorption methods, mainly including vacuum and CFF filtration methods. In addition, according to different refining purification media, it […]

The online refining methods outside the furnace include the MINT method, SNIF method, ALPUR method, FILD method, and so on. Most of these online refining purification methods closely combine degassing and filtration purification. The SNIF method and the ALPUR method use a rotating rotor to blow gas. Make small bubbles uniformly dispersed in the melt. […]

In order to remove the slag and gas in the melt, in addition to the use of flux refining, rotating rotor degassing, and CFF filtration equipment for purification, the control of the smelting process cannot be ignored. Control of Aluminum Smelting Process First, choose dry raw materials (including refining agents) that contain less slag. All […]

Metal refining treatment can remove or minimize the gas and oxide inclusions in the regenerated aluminum alloy melt, so as to improve the degree of purification of the melt. The requirements for the purity of recycled aluminum alloy melts are different due to different varieties and uses. It is usually required that the hydrogen content […]

The aluminum fluxes refining method has a good effect on discharging non-metallic inclusions. The degree of purification by the flux to remove non-metallic inclusions in the melt is not only related to the physical and chemical properties of the flux, but also depends to a large extent on the refining process conditions, such as the […]

Compound purification mainly refers to a new purification method that uses two or more purification technologies at the same time and complements the advantages of various technologies to significantly improve the purification effect and efficiency of aluminum melt. At present, composite purification mainly includes online degassing and filtration purification. The degassing and filtration composite purification […]

The ceramic foam molten Alu filters can effectively filter out the inclusions in the aluminum melt and the hydrogen adsorbed on the surface of the inclusions. The material of the filter mainly includes corundum microporous ceramic tube, glass fiber mesh and foam ceramics. The corundum microporous ceramic tube can filter out the oxide inclusions of […]

The online purification technology of aluminum alloy melt mainly refers to the refining of the aluminum alloy melt out of the furnace. The traditional furnace treatment method has been gradually replaced by continuous purification outside the furnace. The online purification technology of aluminum alloy melt has a good and stable effect, can obtain a better […]

The hydrogen removal purification can generally be described as a bubble floatation method. Through a certain method, a large number of bubbles are created in the aluminum liquid, and the partial pressure difference between the hydrogen in the aluminum liquid and the bubbles is used to make the hydrogen in the aluminum liquid continuously enter […]

The purification treatment of aluminum alloy melt is one of the basic guarantee measures for the production of high-quality aluminum castings, and it is also the main means to improve the comprehensive performance of aluminum alloys. The refining effect of aluminum alloy melt has an important influence on the formation of porosity, pores and inclusions, […]
